    Studs vs. bolts on exhaust header ?

    Hi, ... on an 81' GS750E , while my exhaust system is off with only breaking one exhaust clamp bolt, I was wondering if there would be any reason not to switch from bolts to studs, and if there wasn't, where might I be able to get some. Thanks, any opinion, or advice would be greatly appreciated... ray c. Ps. It is an original exhaust system.

    You can go either way. I prefer studs because there's less chance of stripping out the threads in the head - especially if you're removing the exhaust (semi) frequently.
    Current:
    Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha )

    Past:
    VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
    And a bunch of other crap Yamahas....

      I switched to studs on the exhaust for my 850. I was able to go down to the local NAPA, took one of the old bolts with me, and they hooked me up with a set of 8 studs that worked perfectly.

        Studs are easier to hang the pipe on . You won't crossbreed them either. I put locktite on mine so they don't back out with the nut.

            Suzuki part numbers give the diameter, and length. A stud would need to be longer, of course.

              I believe that a 8mm x 50mm stud worked on my GS850 and GS1000 using a V&H exhaust.

              Darn, with so many daily riders it's hard to decide which one to jump on next.

                Thanks, for the input guys, it didn't seem like there would be a problem, and the common 8mm size that they are, make them readily available at most hardware or supply stores, now that I see. thanks again... ray c.

                  Something to remember is that you can only remove/install steel bolts in an aluminum head a number of times before something gets messed up. If it backs out on it's own, it might pull a few threads out with it aswell. Studs with lock-tight get my vote.

                    You also want to use high temp anti-seize lubricant when installing them.

                      Install them into the head with threadlocker, use the anti seize on the nuts.
